I did test the boot bandwidth (I mean how many MB were transferred). On ext4-over-NFS, with tmpfs-and-overlayfs to make root writable:
I also tested with the kernel netbooting default of rsize=4K to compare. All on 100 Mbps, tcp,timeo=600: | rsize | MB to boot | sec to boot | |-------|------------|-------------| | 1M | 1250 | 84 | | 32K | 471 | 40 | | 4K | 320 | 31 | | 2K | 355 | 34 | It appears matching rsize=cluster size=4K gives the best results. Thank you, Alkis Georgopoulos
